Flat Roof Repair in Toronto

Is it urgent?

Can wait

Flat roofs fail at the joints and the edges, not in the middle. Ponding water finds a seam and then sits on it, which is why the leak inside is rarely under the hole.

Two things override everything else on this page. Do not go up on a roof that is wet, frosted or snow-covered, and do not go up a ladder to chip ice off the eaves — that is the most common way people are seriously hurt around a house in a Toronto winter, and nothing you can do up there beats waiting for someone with the right equipment. And if a ceiling is sagging or bulging, stay out from under it: the water is pooling above the drywall and it comes down all at once.

Signs to look for

Water pooling and still sitting there two days after rain
Seams lifting, blistering or splitting
A leak inside that appears some distance from any obvious damage
The membrane gone brittle or chalky underfoot

How the work is done

Identify the membrane, because EPDM, TPO and torch-on are three different repairs
Trace the leak from the seams, flashings and drains rather than from the stain inside
Clean, prime and bond the repair in the same material as the roof
Clear the drains and check the slope, since ponding is what failed the seam

In Toronto specifically

Toronto's humid continental — long cold winters, humid summers, and a freeze-thaw shoulder season either side climate and its housing stock — Victorian and Edwardian semis through the old city, postwar bungalows and backsplits across Scarborough, North York and Etobicoke, and a downtown core that is almost entirely towers — decide what is worth doing first. Roofing work here falls under the Ontario Building Code, and the City of Toronto handles permits and inspections. Ontario does not licence roofers at provincial level, so the checks worth making are a WSIB clearance certificate and proof of liability cover — both of which a legitimate company will hand over without being chased.

Before the technician arrives

Four things worth doing — and the first one is usually the thing people get wrong.

If you can see the roof safely from a window, note where water stands after rain. That is where somebody should start.
Find out what the membrane is if anyone knows. EPDM, TPO and torch-on are repaired in three different ways.
Clear the drains and scuppers of leaves if you can reach them safely.
Say whether the space below is heated. It changes what the repair has to cope with in winter.

How it works

Three steps, and you decide at the end of them.

1
You call and describe the problem

Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your postal code and we will match you to a licensed company covering your area. There is no form to fill in.
2
A local company takes it from there

They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.
3
You decide whether to go ahead

You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Flat Roof Repair — FAQs

Do I actually need Flat Roof Repair done?

Flat roofs fail at the joints and the edges, not in the middle. Ponding water finds a seam and then sits on it, which is why the leak inside is rarely under the hole.

What does Flat Roof Repair involve?

Finding where the membrane has failed, which is usually a seam, a flashing or a drain, and repairing it in the same material the roof is made of. Patching EPDM with the wrong product is a leak next season.

What makes this different in Toronto?

Toronto's humid continental — long cold winters, humid summers, and a freeze-thaw shoulder season either side climate and its housing stock — Victorian and Edwardian semis through the old city, postwar bungalows and backsplits across Scarborough, North York and Etobicoke, and a downtown core that is almost entirely towers — decide what is worth doing first. Roofing work here falls under the Ontario Building Code, and the City of Toronto handles permits and inspections. Ontario does not licence roofers at provincial level, so the checks worth making are a WSIB clearance certificate and proof of liability cover — both of which a legitimate company will hand over without being chased.

Are the companies licensed and insured?

Yes. We only work with licensed, insured partners in Toronto, and you are welcome to ask to see a licence number on arrival.

What does Flat Roof Repair cost?

It depends on the property, the size of the system and what the inspection finds, so we do not publish a price — a figure quoted on a web page is not one the attending company has agreed to. You get a price before any work starts.
